Sediment erosion is a natural phenomenon. Surface water (river or sea) flows constantly, reshaping landscapes by depositing or eroding sediments. Highly dynamic areas are usually problematic: high sedimentation in dam reservoirs reduces their hydroelectric potential, and severe beach erosion affects the sustainability of coastal developments. These problems are likely to be exacerbated by climate change. The research in hydraulics and sediment transport carried out by Professor Pham Van Bang improves our understanding of sedimentary processes and provides a better picture of current and future trends in the evolution of landscapes that include surface water. Ongoing work is focused on increasing knowledge about erosion processes near coastal developments and the physical laws of cohesive sediment transport.
The approach currently used is based on computational fluid dynamics and experimental modelling using the large wave flume of the Environmental Hydraulics Laboratory and the small wave flume of the CT Scan Lab. Field work is also planned.
